KAISHAN KM211 full hydraulic rock bolting rig is a professional underground anchoring equipment developed for rock bolt construction in low tunnels and underground mines. It is specially suitable for friction bolts, resin bolts and other anchoring works in narrow tunnels with height ≥2m and width ≥2.5m. Equipped with double feeding beams and a 10-rods storage magazine, KM211 can complete drilling, steel mesh installation and rock bolt mounting in one sequence, greatly improving working efficiency. The high-frequency hydraulic rock drill adopts stepped piston technology, which optimizes impact wave transmission, increases drilling speed and reduces drill bit consumption. The rig features a compact and low-profile design, capable of passing through tunnels as small as 2.5m wide and 1.7m high. The four-wheel drive articulated chassis provides excellent maneuverability in confined spaces, while the safety canopy protects operators from falling rocks and debris. Widely applied in underground mining, hydraulic tunnels, roadway reinforcement and infrastructure projects, KAISHAN KM211 is a reliable and cost-effective rock bolting solution for global mining and construction enterprises.
